## Description

And we're reimagining how space can connect us, ensuring security and prosperity. **THE WORK** Lockheed Martin is seeking a talented level 2 Network Engineer with a Secret clearance to work from our Boulder, CO location.
Join a team where your network expertise will keep the sensors that watch the sky running flawlessly, give our warfighters the split-second advantage they need, and help keep the world safe.
SBIRS and the Next-Gen GEO OPIR ground stations form the backbone of the United States' missile-warning architecture.
By delivering near-real-time, high-confidence detection of ballistic missile launches and other hostile trajectories, these systems provide life-saving early warning for the warfighter, enable rapid decision-making, and support cueing of defensive interceptors and command-and-control assets.
The Overhead Persistent Infrared (OPIR) Infrastructure Team is seeking a Network Engineer to design, build, and sustain the ground-station platform that supports both SBIRS and the Next-Gen GEO OPIR ground stations.
In this role you will work closely with software, security, and mission engineers to deliver ultra-reliable, secure, and scalable ground-systems that enable continuous infrared surveillance and missile-warning capabilities for legacy and next-generation satellite constellations.
As Network Engineer you will: * Design and plan network communications systems. * Provide specifications and detailed schematics for network architecture. * Provide specific detailed information for hardware and software selection, implementation techniques and tools for the most efficient solution to meet business needs, including present and future capacity requirements. * Conduct testing of network design. * Maintain technical expertise in all areas of network and computer hardware and software interconnection and interfacing, such as routers, multiplexers, firewalls, hubs, bridges, gateways, etc.
